Gateway
Gateways describe how sequence flows split or join within a process. They determine the behavior of incoming and outgoing connections. In ARIS they are represented as objects of the Rule type.
Similar to events, various types of gateways can be specified. Depending on the type, further symbols are shown in the center of the Gateway symbol.
A few differentiating gateway symbols:
Gateway types
The BPMN specification stipulates that a number of gates must be defined for each gateway. In ARIS the number of gates is determined by the number of incoming and outgoing connections. Therefore, gate-dependent attributes are specified for the incoming and outgoing sequence flow connections of the rule.
A special case is the complex gateway for which the Incoming condition and Outgoing condition attributes are defined. These attributes are required if there are multiple incoming or outgoing sequence flow connections for a given gateway. The attribute content of the incoming condition can contain sequence flow names and process properties (data). The outgoing condition contains references to sequence flow IDs and process characteristics (data).
